You could interpret this the other way - Why has Jeff Dean been snubbed by the Nobel committee? Why hasn't Larry Page gotten a Nobel for inventing the search technology that half the planet now depends on? I don't know what category to put that one in, but there's some important results in lightspeed-limited communications in "The Datacenter as a Computer" that would be worth extending the Physics category for.
It was better search than other search options at the time, but was quickly an advertising company. It's also too bad that that it was so dominant early, because there used to be 4-5 search Enginess and their results were very different and you could find things in non-google results that you couldn't get from google (and vice versa).
You're not wrong, but it didn't last. Google jumped the shark in its first decade. I remember giving an internal presentation in 2010 or 2012 about how little of the screen real estate in a Google search result was actually search results.
